Answer:

21.5%

Step-by-step explanation:

60 and 112 repsectivly

60x(1.15) + 112(1.25)

69 (hehe nice) + 140

so 209 total honour roles compared to 172 last year

209/172 = 1.215116

subtract 1

.215116

multiply by 100

21.5116%

21.5%

Ray Of Light [21]
\bf \textit{Amount for Exponential Decay using Half-Life}\\\\
A=P\left( \frac{1}{2} \right)^{\frac{t}{h}}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &10\\
t=\textit{elapsed time}\to &1000\\
h=\textit{half-life}\to &1599
\end{cases}
\\\\\\
A=10\left( \frac{1}{2} \right)^{\frac{1000}{1599}}
